Help !!!! 1997 5.7 188000 . After filling up the suburban with gas it will not start. It was running great . I turned it off to get gas and now it won't start . It turns over but doesn't crank . Fuel pump and filter have been replaced I had a extra relay in the vehicle but no luck. I'm stuck at the gas station . Anyone have any suggestions.
I also pressed the valve on the fuel line next to the engine and fuel does come out .

 

check for spark at one of the plugs with a proper spark tester.

 

Thanks for the feedback Tech2. I'll check that . I had it towed to the house and switched vehicles. We were headed out of town on a family weekend getaway. Luckily I wasn't too far from town. I was enjoying having all sorts of extra room in the suburban. I can't say that about my Subaru Outback 3 adults and 2 kids with car seats. It's tight . I'll update when I get the problem solved .
